When a wuxia novel says Zi hour, a drama subtitle says “third watch,” or a game asks you to wait one shichen, the safest translation is a range or duration, not an invented exact timestamp. One shichen is about two modern hours; a named branch hour is a two-hour window; ke depends on the time law; and geng usually refers to a night watch unless the scene establishes another system.
In brief: Use “Zi hour (11 p.m.–1 a.m.)” on first mention, then “Zi hour.” Translate one shichen of duration as “about two hours.” Render ke as a mark or quarter only when the convention is clear. Treat the five night watches as approximate and preserve ambiguity when the story uses time to create atmosphere rather than schedule a train.

The fast branch-hour cheat sheet
| Branch | Chinese | Standard modern range | Natural scene cue |
|---|---|---|---|
| Zi | 子时 | 11 p.m.–1 a.m. | around midnight |
| Chou | 丑时 | 1–3 a.m. | deep night |
| Yin | 寅时 | 3–5 a.m. | before dawn |
| Mao | 卯时 | 5–7 a.m. | dawn / sunrise |
| Chen | 辰时 | 7–9 a.m. | morning |
| Si | 巳时 | 9–11 a.m. | late morning |
| Wu | 午时 | 11 a.m.–1 p.m. | around noon |
| Wei | 未时 | 1–3 p.m. | early afternoon |
| Shen | 申时 | 3–5 p.m. | late afternoon |
| You | 酉时 | 5–7 p.m. | sunset / early evening |
| Xu | 戌时 | 7–9 p.m. | evening / dusk |
| Hai | 亥时 | 9–11 p.m. | settled night |
The ranges follow the standard mapping published by the Hong Kong Observatory. They are the right default for an English reader, while the scene cue is often the more natural choice in dialogue.

When shichen means a duration
Shichen (时辰) can name one of the 12 branch periods, but it can also express elapsed time.
- deng yige shichen (等一个时辰): wait about two hours;
- ban ge shichen (半个时辰): about one hour;
- san ge shichen (三个时辰): about six hours.
Context tells you whether the speaker names a period or a duration. “Meet at Wu shichen” points to a part of the day. “The medicine takes one shichen” describes elapsed time.
In fantasy dialogue, “an hour” may sound smoother, but it changes the duration by half. If timing affects the plot or gameplay, preserve “two hours” or introduce shichen in a glossary.
How to translate ke
Ke (刻) is harder because its value changed. In a 100-ke day, one ke is 14.4 modern minutes. In a 96-ke day, one ke is 15 minutes, matching the modern Mandarin sense of a quarter hour.
Choose among three strategies:
- Keep the term: “after three ke,” with a note when historical texture matters.
- Use an approximate phrase: “a short while later” when exact conversion is not supported.
- Use minutes: only when the work establishes a 15-minute or other convention.
The famous wushi sanke is exactly why caution matters. It is often rendered “11:45 a.m.” or “noon, three quarters,” but scholarship shows its execution-time fame is heavily literary. Read Was Wushi Sanke Really Execution Time?.
How to translate geng and dian
Geng commonly names one of five night watches. A practical subtitle chart is:
| Watch | Approximate range | Natural translation |
|---|---|---|
| First watch | 7–9 p.m. | early night |
| Second watch | 9–11 p.m. | late evening |
| Third watch | 11 p.m.–1 a.m. | around midnight |
| Fourth watch | 1–3 a.m. | after midnight |
| Fifth watch | 3–5 a.m. | before dawn |
The word dian (点) can mark a counted beat or subdivision in watch reporting. “Third watch, second beat” preserves the structure without promising a modern minute.
Actual watches could adjust with seasonal night length. In maritime manuals, geng could also measure voyage time across a full day. Genre decides which rule is active. See Why Chinese Night Watches Changed with the Seasons and Geng at Sea.
Dialogue, subtitles, and interface labels
Different media need different levels of explanation.
Novels and essays
Introduce the term once: “at Mao hour, the dawn period from about five to seven.” After that, keep “Mao hour.” The reader gains vocabulary without repeated footnotes.
Subtitles
Space is limited. Translate the scene’s function: “at dawn,” “near midnight,” or “in about two hours.” Use the named branch when it matters to a riddle, ritual, alibi, or cultural clue.
Games
If the interface runs on a fixed cycle, show both systems: Zi · 23:00–01:00. If one in-game shichen passes faster than two real hours, label it as in-game time rather than historical conversion.
Museum or educational copy
Prefer transliteration plus definition. Preserve uncertainty and identify the dynasty or object whenever a fine conversion is important.
Five common translation mistakes
1. Turning every shi into 60 minutes
In this context, a traditional shichen is about two modern hours.
2. Translating Zi hour as “yesterday” or “today” automatically
Zi crosses civil midnight. A source may need an explicit date-boundary convention.
3. Making every ke exactly 15 minutes
That is one useful convention, not every historical system.
4. Fixing every geng to two hours
Five night watches could vary seasonally, and maritime geng follows a different rule.
5. Treating an animal as a clock mechanism
The zodiac animal is a mnemonic correspondence attached to an Earthly Branch. Rat hour does not mean rats mechanically determine midnight.
Frequently asked questions
How long is one shichen in a Chinese drama?
About two modern hours unless the fictional world defines its own time scale.
What does Zi hour mean?
It is the midnight-centered branch period, conventionally 11 p.m.–1 a.m.
What is “third watch” in a wuxia novel?
It usually evokes the middle of the night, conventionally around 11 p.m.–1 a.m., but the historical watch could vary by season.
Should subtitles keep pinyin?
Keep it when the term matters culturally or narratively. Use a natural time phrase when speed and clarity matter more than terminology.
Are branch-hour ranges historically exact?
They are a standard modern mapping. Exact historical reckoning can depend on the period, place, time law, and source.
Translate the function, preserve the system
A good translation tells readers when a scene happens without erasing how the source organizes time. Give a range when the term names a period, a duration when it counts shichen, and an explicit caveat when ke or geng depends on a historical convention.
